A printing apparatus includes a feeding roller configured to feed a printing sheet stacked on a stacking unit, a conveyance roller configured to convey the printing sheet fed by the feeding roller, a printing unit configured to print the printing sheet conveyed by the conveyance roller, a conveyance control unit configured to control conveyance of printing sheets so that the trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and the leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit configured to determine whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet.

A sheet feeding device includes a support, a rotation driver, a guide, a support shaft, a biasing member, a leading end sensor, a roller, an outer diameter sensor, and circuitry. The circuitry causes the rotation driver to rotate a spool in a winding direction to determine a timing at which a signal change rate exceeds a change rate threshold as a passing time at which a leading end of a continuous sheet passes through the leading end sensor, causes the rotation driver to rotate the spool by a rotation angle in the winding direction, from the passing time, to position the leading end of the continuous sheet at a feeding start position, and rotates the spool in a feeding direction to feed the continuous sheet from the feeding start position along a guide portion. Further, the circuitry changes the change rate threshold based on an outer diameter of a roll.

A printing apparatus includes a print unit configured to print an image on a print medium, a conveyance unit configured to convey a print medium to the print unit, a first feed unit configured to feed a first print medium to the conveyance unit, a second feed unit configured to feed a second print medium to the conveyance unit, and a control unit configured to control the first feed unit, the second feed unit, and the conveyance unit. The control unit is configured to start, in a state in which the first print medium is being conveyed by the conveyance unit, feeding of the second print medium to the conveyance unit by the second feed unit.

A sheet feeding apparatus for feeding sheets is provided with a multi feed detecting section for detecting multi feed of conveyed sheets in a predetermined detection position of a conveyance path, and first and second discharge sections to which multi-fed sheets with the multi feed detected are discharged, and corresponding to one of a front end position of the multi-fed sheets at the time the multi feed detecting section detects the multi feed of sheets, a sheet storage state of the second discharge section, sheet storage states of the first and second discharge sections, a size of sheets and weighing, selects one of the first and second discharge sections to discharge the multi-fed sheets to the selected discharge section.

A printer includes: a printing head; a conveyor; a cutter for cutting the medium to provide a segmented medium; a discharge roller; a counter roller; a sensor for detecting whether the segmented medium remains between the discharge roller and the counter roller; and a controller configured to perform: setting an operation mode to one of a first mode and a second mode depending on a medium kind; controlling the printing head and the conveyor to perform a first print control on the medium; controlling the sensor to detect whether the segmented medium has been removed; and permitting a second print control to be performed. When the operation mode is the first mode, the second print control is permitted after the sensor detects whether the segmented medium has been removed. When the operation mode is the first mode, the second print control is permitted without controlling the sensor.

In some examples, a gimbaled monoclamp can include a housing including a first opening, a second opening, and a pivot point, a clamp disposed at least partially in the housing and including a first pad and a second pad to extend through the first opening and the second opening, respectively, and a pin extending through an opening in the clamp into the pivot point to couple the clamp to the housing in a gimbaled manner.

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

The printer is a printer for printing on a label continuous body including a label detecting unit having a light-emitting portion configured to emit a detecting light and a light-receiving portion configured to receive the detecting light and a control unit configured to adjust a light emitting output of the detecting light in the light-emitting portion, so as to bring an output voltage from the label detecting unit when the light-receiving portion receives a detecting light through the liner to which the label is not temporarily attached, closer to an output voltage from the label detecting unit when the light-receiving portion receives a detecting light through a state in which there is no label continuous body between the light-emitting portion and the light-receiving portion.
